This article compares diffusion models used to describe seedless grape drying at low temperature. The models were analyzed, assuming the following characteristics of the drying process: boundary conditions of the first and the third kind;constant and variable volume, V;constant and variable effective mass diffusivity, D;constant convective mass transfer coefficient, h. Solutions of the diffusion equation (analytical and numerical) were used to determine D and h for experimental data of seedless grape drying. Comparison of simulations of drying kinetics indicates that the best model should consider: 1) shrinkage;2) convective boundary condition;3) variable effective mass diffusivity. For the analyzed experimental dataset, the best function to represent the effective mass diffusivity is a hyperbolic cosine. In this case, the statistical indicators of the simulation can be considered excellent (the determination coefficient is R2 = 0.9999 and the chi-square is χ2 = 3.241 × 10–4).

The Cucurbita maxima Duchesne is a vegetable crop plant cultivated and maintained by traditional Amazon communities, Brazil. The situation is worsened by the possibility of disappearance of local populations and genetic variability of this specie, taking into account the today changes promoted in family farming. The aim of this study was to estimate the current levels of genetic variability of local cultivars through the use of molecular markers (Amplified Fragment Length Polymorphism—AFLP). We chose to collect in two distinct micro regions in order to identify possible influences of geographic isolation and different levels of market requirements in the conservation of the genetic variability of the C. maxima. For the molecular analysis, bulk samples of fresh leaves of 15 plants/half-sibling family were collected in paper bags. There were 34 samples from the half-sib families. The analysis of the results half-sib obtained by methods of estimation of genetic variation by molecular markers shows that the forms of cultivation and management adopted by family farmers maintain the identities of the local/landraces (native cultivars) and, at the same time, the levels of diversity for the assurance of adaptability macro-environmental.

The uncertainty about the future of firms must be modeled and incorporated in the valuation of enterprises outside the explicit period of analysis, i. e., in the continuing or terminal value (TV). There is a multiplicity of factors that influence the TV of firms which are not being considered within current evaluation models. This aspect leads to the incurring of unrecoverable errors, thus leading to values of goodwill or bad will far away from the substantial value of intrinsic assets. As a consequence, the evaluation results will be presented markedly different from market values. There is no consensus in the scientific community about the method of computation of the TV as a forecast in an infinite horizon. The size of the terminal, or non-explicit period, assumed as infinite, is never called into question by scientific literature, or the probability of business bankruptcy. This paper aims to promote a study of the existing literature on the TV, to highlight the fragility of the evaluation models of companies that have been used by the academic community and by financial analysts, and to point out lines for future research to minimize these errors.

Small WWTP (wastewater treatment plants) are frequently located, by necessity, in remote and isolated sites, which increases the difficulty of its energy supply. This paper describes a case study which is a step by step procedure concerning the evaluation of the wind potential of sites that are dependent of in-situ energy generation, as well as, on the utilization of the potential wind energy in Magoito WWTP. The adopted methodology comprised the collection of one year of in-situ wind data and its validation by comparison with historical data of more than 10 years of a nearby anemometric station. The data provided by the two anemometric stations was statistically treated and allowed the analysis of the results from the two stations. These results are promising in terms of wind availability and velocity. Finally, the study comprised the simulation of the local wind conditions for a considerable larger area in order to find the best site for locating a wind turbine.

The adoption by health professionals to the practice of patient isolation is a decision that reduces patients’ risks of occupational exposure to potentially contaminated biological material and prevents nosocomial infections. Verify the compliance of health professionals to the practices of contact precautions in patients colonized by microorganisms in a teaching hospital. This was a prospective observational cohort study in a special-sized hospital located in southeastern Brazil. The observation of health professionals in delivery of health care to patients with contact precaution was performed regarding hand hygiene, use of overcoat, glove, and mask. We carried out 1502 observations involving the following professional categories: nursing technicians and/or nursing assistants (n = 1028;68.4%), nurses (n = 200;13.3%), physical therapists (n = 185;12.3%), and physicians (n = 89;5.9%), totaling 971.8 hours. Regarding the level of compliance of professionals to contact precaution practices with hand hygiene after the procedures, the use of overcoats, gloves, and masks, all were statistically significant (p Klebsiella pneumoniae was the most positive pathogen identified in laboratory tests. This study provided the mapping of the compliance of health professionals to the practices of contact precautions in order to support a safer management of patient care reducing the risks of Healthcare-Associated Infections (HAI). This study also showed that health professionals are using practice management to deal with their behavior to protect their health.

Objectives: This study proposes to evaluate risk factors for kidney disease in HIV patients treated chronically and correlate with microalbuminuria measurements. Methods: Review charts and analyses of microalbuminuria in subgroup of HIV patients treated at Ceara/Brazil. Results: 149 patients, 69.1% male, mean 38.5 years old, infection mean 86.8 months. Mean Creatinine Clearance 110.2%, Creatinine 0.97, Urea 27.76 mg/dl, CD4+ 600.37 cels/mm3 and detectable viral load 530.59 copies with 61.7% undetectable. Mean Dosages of microalbuminuria/24h 147, 46 ± 820, 45 (N = 48) and microalbuminuria (mg/dl) 32.05 ± 85.25 (N = 43). Kidney Diseases Classification analyses evidenced 6.4% patients in stages ≥3 and 6.2% presented altered Microalbuminuria/24h. Patients using Tenofovir (TDF) 27.27% had Stage 2 and protease inhibitors (PI) had 4.1% in Stage 3. Proteinuria was observed in 5% stage ≥3. Association PI/TDF had 4.1% in Stage 3. No statistical difference between CD4 > or 3 and microalbuminuria/24h > 300 mg (p = 0.69);detectable/undetectable viral load and microalbuminuria/24h (p = 0.63) or stage ≥3 (p = 0.17);relation to Diabetes or arterial hypertension and microalbuminuria 24 h (p = 0.5 and p = 0.21);relation stage ≥3 and microalbuminuria/24h (p = 0.33);relation HIV diagnoses >/ or or < 50 years and microalbuminuria/24h (p = 0.55) or microalbuminuria mg/d (p = 0.32). Relating comorbidities risk (Diabetes Mellitus plus Systemic Arterial Hypertension) to Kidney Diseases, it was found that 55.5% patients in Stage 3 or above with comorbidities compared with 15% with comorbidities in lower stages (P = 0.005). Nevertheless, comorbidities presence was not associated with microalbuminuria (p = 0.08). Conclusion: Kidney disease is a real risk for HIV patients and stages ≥

Medicinal plants have been presented as a valuable source of preservation of human health. In special, Stryphnodendron barbatiman has been employed due to its antimicrobial activity. This plant is rich in tannins and has been used in popular medicine for the treatment of gastrointestinal disorder, treatment of lesions, and also as anti-inflammatory microbicide. Citrobacter freundii is a member of the family Enterobacteriaceae and is one of the major causes of opportunistic infections. This microorganism is a bacterium (bacillus) aerobic gram-negative with a length in the range of 1 to 5 mm. C. freundii is commonly found in water, soil, food and occasionally in the gastrointestinal tract of animals and humans. In this paper, we have demonstrated the antibacterial activity of S. barbatiman by observing cellular death by using inhibition halo approach. Atomic force microscopy and FT-IR spectroscopy results suggested that interaction between the main active components of S. barbatiman with cellular wall of C. freundii gives rise to cellular wall damage, and then leads this microorganism to death.
